I came across this old Carole King song. Not my main musical style interest, but something I grew up with and I do appreciate it. So I noticed this little piano riff at the end of the verse lyric, and I wondered “Is that the hook?” I can only describe it as a fast E, G, A, A, A, G, E melody. It seems to jump out and cement the song, though only being a brief flourish in the instrumentation. So that piqued my curiosity as to what actually constitutes a hook. We can probably easily name them when we hear them, but what’t the definition or essential nature of such “ear candy”? My understanding is that Pop and Commercial songs have to have a hook, if they want to be successful.
Do you know of other examples, both obvious or cleverly concealed?
